Fireworks - How Big and How High
Researched and Designed by Ghergich & Co. http://ghergich.com
When a firework explodes, two things have to happen; the shell has to reach its intended height and then it has to be exploded at that height. The shell is placed in a tube called a mortar and a fused gunpowder charge under the shell propels the shell into the sky. There is another fuse attached to the shell called a time delayed fuse, and this fuse ignites the stars inside the shell after the shell is propelled into the sky.
